Original application'fled November 15. 1919. Serial No. 338,335. Divided and this application filed v June 12, 1920./Se'ria1 No. 388,477.

Be it known that I.iIro.\i.. I. DUFFY. a citizen ofthe l1United.States. residing` in the city of (lhicagogfin the county of Cook aud the State of Illinois. have, invented certain new and useful Improvements iu' Disk- IVheel Rims, of which thefollowiug is a specification. reference being had to theaccompanying' drawings, forming a part thereof.

' This application is a division of my pending application. Serial No'. 338.335. filed November 15, 1919. y

The purpose of this invention is-to provide improvement in disk wheels. particularly with respect to the rim or seat for the tire. It consists in the elements and features of construction shown and. described, as indicated inthe claims.

In the drawings:

Figure 1 is an inner side ele 'ation of a wheel embodying this invention.

- Figure 2 is a section at thley line. 2-2. on.

Figure 1. v

In' the structure shown iu the drawings the wheel comprises in lieu of' spokes. a disk web. 1, to which the parts are secured which constitute a two-part rim or tire piece. Thedisk. l. is formed with a peripheral flange. 3, to afford secure-ment to it of the rim ineinbers. Said rim members comprise the memfber. 4. which is provided with a single lateral tire-retaining fiange. while. the other tire-retaining flange, G, is. formed on a -separate element, 2. of annular form which has a portion, 7. which extends obliquely from the retaining' flange, 5. into Contact with the web, l. of the wheel. Said web is shaped substantially as shown in Figure 2 tol provide the flange, 3, above mentioned, for permanent securement thereto of the rim mem ber, 4; but in the angle between the flange,

3, and-the annular portion, 8, of the Web,-

there is welded or otherwise secured a block,

9, bored and threaded to receive a clamp drawn into place or. readily [removed permit removalof the tire. Theoblique arrangement of the annular pa1*t, 7, serves to stiflen the connection between the diskvand the rim aud gives the disk a broader footing on the rim.

I claim: y

1. In a vehicle wheel, av rim -member comprising' a member formed with a tire-retaining flange atone edge, in combination with a web of the wheel at the circumference of which the rim member is rigidly positioned. said web extending from the rim in a'plane offset from the middle toward the flanged edge of said riml member, and a removable rim member formed with an opposing tire-retaining flange and having an annular part which extends into lodgment against the wheel web at a dis. tance inward from the rim toward the wheell center,` and fastening' screws which clamp said annulaipart of said second rim member at its greater and lesser 'eircumferenees respectively. against the margin of the first rim member opposite the {iange thereof and against the wheel web at a distance inward from the rim.

2. In a vehicle wheel in combination with an annular web member positioned'generally in the mid-transaxial plane of' the wheel. a rim-member formedv with* a tirere-tainiug flange at one edge and secured to the web member at the outerperiphery of the latter, and a removable rimmembeiformed with an *opposing tire-retaining flange'andan annular portion, said annular Aportion extending obliquely` from the. tire- 'retaining' Harige of said member inward with respect to the wheel and vtoward said mid- 'plane and into contactV with .the web of the wheel, and threaded means'secured in the angle between Vthe web of the wheel and said first mentionedrim member to receive fastening means passing through said Oblique annular portion.A

In a vehicle wheehin combination with a disk-like web member having a peripheral portion offset laterally from the portion interior thereto, and having a peripheral fiange extending from said offset portion toward said -mid-plane; 'a rim member formed with a tire-retaining flange and seatedon said flange of thek web member; a removable rim member havingv a counter'- pa-rt tire-retaining flange and an annularv l' ortion extending obliquely from said flange lnward with. respect to the'wheel and toward the plane vof the opposite tire-retaining flange, and I"seated on the web member at a 5 distanceinward from the tire seat; whereby there is enclosed between said annular flange and the tire seat at the web member a space AWhich in radial section of the Wheel-is in general triangular, and fastening means extending through said oblique annular port'ion into said Vtriangular space to secure the removable rim member .to the web and clamp said annular flange toward the op- `posite angle of said triangular space.

In testrmony lwhereof, I have hereunto lset my hand at Chicago, Illinois, this 7th yday of June,l 1920,

THOMAS DUFFY.
